CELL ORGANELLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Proteins are produced by these small, round (grain-shaped) organelles.
A
Chloroplasts
B
Lysosomes
C
Ribosomes
D
Vacuoles
Explanation: 

Detailed explanation-1: -The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Detailed explanation-2: -Ribosomes are small grain-shaped organelles that produce proteins. Proteins are important substances in cells.

Detailed explanation-3: -The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis.

Detailed explanation-4: -Protein synthesis Synthesis of new proteins starts in the nucleus, where ribosomes get their instruction to begin the process. Sections of DNA (genes), encoding a specific protein, are copied over to messenger RNA (mRNA) strands in a process called transcription.

Detailed explanation-5: -A ribosome is the cellular machinery responsible for making proteins.
